ShopSavvy is being billed as the latest and greatest in barcode scanning mobile technologies. The Windows Phone 7 application uses your Windows Phone camera to take a picture of any barcode and ShopSavvy will provide you with a list of online and local prices.
Compare prices to shop or use competitors' prices to reduce your costs. Results are returned with listings found with online retailers, as well as local merchants. Shopsavvy will also find any reviews on the merchandise and a map to local retailers offering the items.
Trouble scanning the bar code? A recent update adds the ability to manually enter the code's numbers.
Shopsavvy is a free application and you can download it here (opens Zune) at the Marketplace.
